China's Basic Principle

The main lesson of Chinese desertification control projects is simple: don't start with trees. First, you need to stop the sand flow, create a rough surface, accumulate organic matter and moisture, and then introduce plants.

The principle of consistency

First the surface, then life

For DREVO, the Chinese approach is important not as a copycat technology, but as an engineering discipline. The green corridor must be built in a sequential manner: sand is fixed, the surface begins to retain dust and water, a biological crust forms, and then shrubs and trees appear.

Sand fixation begins as a manual engineering exercise, not as tree planting.

The wind barrier complements the mesh and reduces sand drift in exposed areas.

The logic of the Chinese approach and its adaptation for DREVO

Stage	What is being done?	Why is this necessary?	Adaptation DREVO
1. Sand fixation	straw, twig or biodegradable cages	decrease in wind speed at the surface	local grids, palm waste, branches, stone lines
2. Roughness	stones, microrelief, shallow depressions	retention of dust, dew and rare precipitation	crescent moons, zai-pits, contour lines
3. Organics	straw, compost, plant residues	transition from inert sand to living substrate	algae, compost, mulch, dry plant residues
4. Biocork	mosses, lichens, cyanobacteria and microbiology	surface bonding and moisture retention	test biocrust areas in protected areas
5. Landing	first bushes, then trees	reducing the risk of planting failure	tamarisk, acacia, atriplex, then more valuable crops

1. Sand fixation

The first step is to stop the horizontal movement of sand. In Chinese practice, grids are often used for this purpose: the material is laid in squares and partially buried in the sand. Inside the grids, the sand slows down, begins to trap dust, and becomes suitable for the next layer.

the wind at the surface becomes weaker;

the sand stops moving freely;

dust and organic matter are retained in the cells;

The site receives a physical basis for biology.

2. Biocrust and living surface

Once the surface has stabilized, a biological soil crust can be applied. This is a layer of moss, lichen, cyanobacteria, and microorganisms that binds the sand and helps retain moisture. For DREVO, this is not a decorative element, but the foundation of an ecosystem.

Biocrust transforms loose sand into a cohesive living surface.

The microstructure of the biocrust shows how sand particles are linked by biological threads.

Organic matter and mulch speed up the transition from sand to soil layer.

3. Water is connected after stabilization.

In coastal conditions, the Chinese logic is complemented by ocean resources: fog, dew, and solar desalination. However, the water should be supplied not to open sand, but to a prepared surface with cells, mulch, microrelief, and wind protection.

Mist eliminators enhance the DREVO model after the surface has already acquired the ability to retain moisture.

Spot watering is only useful where the root is protected and the soil does not overheat.

Small-scale desalination can power test modules, but does not replace sand protection and soil.

What changes after 1-3 years of preparation

Indicator	Change	Practical meaning
Sand movement	is decreasing	less snow drift on roads, grids and young plantings
Organics	accumulates in cells	the basis for soil formation appears
Humidity	better retained in microrelief	plants receive a more stable regime
Surface temperature	reduced by cover and shade	less stress for roots and microbiology
Plant survival	is increasing	the landing becomes planned, not random

Practical diagram for the DREVO pilot

Step	Action	Control result
Step 1	mark out 1x1 m or 2x2 m cells	sand moves less in the wind
Step 2	add stones, holes and organic matter	dust and moisture are trapped in the cells
Step 3	Connect the project's water: fog, dew, solar desalination	a minimum stable water regime appears
Step 4	introduce resistant shrubs	the first living barrier is formed
Step 5	only then plant trees	trees are part of a protected system

The main conclusion

Chinese experience is valuable not for a single technology, but for the process itself. For DREVO, this means: a green corridor begins not with a tree, but with a surface that ceases to be shifting sand and gradually becomes living soil.

The working formula of the project: structure + biology + water + time.
